This news brief from March of 2008 describes scientists' discovery of a new mammal species, a giant elephant shrew. Though elephant shrews resemble regular shrews, recent genetic evidence suggests that elephant shrews actually sprang from a much older (and perhaps more charismatic) branch of the tree
of life - the one belonging to elephants and their relatives.

- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- Geological change and biological evolution are linked.
- Tectonic plate movement has affected the evolution and distribution of living things.
- An organismís features reflect its evolutionary history.
- There are similarities and differences among fossils and living organisms.
- Not all similar traits are homologous; some are the result of convergent evolution.
- A hallmark of science is exposing ideas to testing.
- Scientists test their ideas using multiple lines of evidence.
- Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data.
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- Classification is based on evolutionary relationships.
